How long does it take for my body to start burning fat from walking?

The difference lies in the fact that, when exercise is performed for a longer period and at the appropriate intensity, the rate of energy mobilization from excess fat increases, according to the health website Verywellfit (USA).

When you start walking, your body typically prioritizes using glucose in the blood and glycogen stored in the muscles for energy. These are readily available fuel sources. In addition, blood fat and excess body fat are still used, but at a lower rate.

Combine multiple energy sources during exercise.

Studies show that the body always combines multiple energy sources during exercise. When performing prolonged endurance exercises at moderate intensity, the oxidation of fatty acids gradually increases over time.

For most healthy individuals, after about 20-30 minutes of continuous walking at a moderate pace, the body begins to use more fat and excess body fat for energy. As the amount of readily available glycogen decreases, the body will mobilize more stored fat.

People who exercise regularly are more effective at mobilizing excess fat.

However, this point in time is not the same for everyone. It will vary depending on age, physical condition, exercise habits, walking speed, and whether you have just eaten or are hungry. People who exercise regularly are more effective at mobilizing excess fat than those who are less active.

If the goal is fat loss, maintaining a walking time of 30-60 minutes is often more effective than shorter workouts. Longer exercise sessions help the body burn more calories and extend the time that excess fat is used as fuel.

Walk for 30 minutes a day.

The non -profit Mayo Clinic (USA) recommends that adults maintain at least 150 minutes of moderate-intensity endurance exercise per week. For many people, walking for about 30 minutes a day is a realistic goal and easier to sustain long-term than high-intensity forms of exercise.

Walking can help reduce fat, but the final results depend on your overall lifestyle. Even with regular walking, overeating or insufficient sleep can still hinder weight loss.

To optimize effectiveness, walking should be combined with a balanced diet, sufficient sleep, strength training to maintain muscle mass, and limiting prolonged sitting during the day, according to Verywellfit.
